The star explained she now wants a reduction, saying: “My boobs are crushing me....I'm desperate to go back to normal. I'm downgrading and going a little smaller, to a D or a double D.”

Montag revealed that her massive breasts make it hard to keep fit. She said: “I'm obsessed with fitness but it's impossible to work out with these boobs. It's heartbreaking. I can't live an everyday life.”

In other bad news for Heidi, her ex Spencer Pratt is still threatening to release a sex tape featuring her.

A recent Tweet from Pratt said: “John Lennon had a guitar. Picasso had an paintbrush. And I have a sex tape.”

He also joked: “The sex tape will not feature any bisexuality. It will however feature trisexuality. Also - a triceratops.”
